How to test iPhone app with different n/w speed

I wants to test my iPhone app performance with different n/w speed on device.

开发者_如何学运维can any one suggest me any Mac application or test environment where I can test it?

Currently I am testing app by creating my Mac as hot spot.

If you don't need very fine granularity regarding the tested speeds you could just load the App onto the device and test with Wifi, 3G and Edge/GPRS. Most of the times this should suffice I'd say, its also the speeds users will likely encounter in real life.

I had a network issue when it would drop a connection mid transfer... my top tip was put the app on your test device and chuck the phone in a microwave ( needless to say without turning it on of course! ) and look at the crash logs for what on earth happened.

The faraday cage works a charm to test that 'travelling in a train' style loss of signal that inevitably happens outside of the office environment.

Try http://mschrag.github.com/ to test in the simulator

I'd say test it on the Real Device first. If your App is consuming Web Services somewhere , try to test that for times.

If you are using Xcode 4.1 on Lion, you can use the Network Link Conditioner pref pane provided. It can be found under /Developer/Applications/Utilities/Network Link Conditioner.
